Specification of Letters iatent. Patented Oct, 19, 1915,

Application filed. December 31, 19,13. SeriaLNo. 809,662.

To all whom it may concern land, have invented certain Improvements in Machines for Shaping the Materials of the Rear Portion of a Boot or Shoe Upper, of which the following description, in con-- nection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to shoe making machinery and particularly to machines for molding the rear portions of shoe upper materials preparatory to the pulling-over and lasting operations. Machines for performing such operations have been proposed as disclosed by British specifications 26,698 of 1909 and 23,685 of 1912, and the object of this invention is to provide a machine em todving certain improvements over prior machines which increase its convenience for use and efiectiveness of operation.

With this object in view, an important feature of the invention consists in an organization and arrangement of a molding machine by which there is provided an open space below and around the inside formerto permit the presentation of the work thereto from underneath. V

In accordance with a further feature of the invention the parts are so arranged that the operator can conveniently look down into the work to see that the upper mate-.

rials are properly arranged about the inside former before the outside former is closed. Preferably the inside former is so.

constructed and supported that a work receiving space is provided in front of'those portions embraced by the work so that the forepart of the upper is not distorted while the rear partis being molded. Ingenuity has been required to support the inside former for a shoe upper so that these condi tions are fulfilled vfor clearance all around,

below and in front of the inside former,

while furnishing adequate strength to resist the forward pressure of the outside formers in doing then work.

Another feature 'of the invention relates to novel and very effective means for producing compression of the upper materials between the flange forming wipers and the heel seat face of'the inside former. conditions above'suggested as desirable for presenting the work to the inside former The V and forrigidity of mounting for that former render it advisable to maintain the inside former stationary, as distinguished from the vertically movable inside formers heretofore proposed. This introduced the problem of producing a satisfactory organization for depressing the wipers with adequate power after they had been advanced over the shoe bottom. Because of the manner in which they are usedand the occasions for replacewipers which is movable bodily over the formers, and means is comprised in said mechanism for depressing the wipers relatively to other parts of the mechanism for effecting compression of the overwiped stock. bodied in a wipercarrying slide containing a frame which is movable up and down in the slide, and operating mechanism, shown as toggles, for depressing the frame and the wipers relatively to thebody portion of the slide to irondown the stock. I

In accordance with a further feature of this invention connections are provided through which the direction of application of the force for advancing and closing the wipers is changed as the wipers approach the end of such movement and is caused to take effect in depressing the wipers. This result is herein obtained by connecting the wiper advancing means with the wlper depressing toggles and providing devices which are operative to prevent full straightening of the toggles until. substantially the end of the stroke of said means.

This feature of the invention is em- Another feature of this invention relates the outside formers. This mechanism comprises grippers engaging the upper mate rials, preferably including the ends of the heel stiffener, in the shank at each side of the inside former, holding these parts at the right elevation, and pulling them forwardly to cause them snugly and smoothly to embrace the inside former before the outside formers close. In the illustrated embodiment of this feature of the invention means is provided for closing and moving the grippers by the same treadle or other controller that is caused by a further movement to start the pow r mechanism for closing the outside formers and operating the wipers. The machine is also so organized that the grippers are caused to release the upper automatically from pulling strain during the final part of the molding operation and also preferably to, retreat to an out-of-theway position after which they are returned automatically to work receiving position at the end of the molding operation.

Another feature of the invention relates to novel mechanism for operating the wipers to first close inwardly over the sides of theheel end of the material and thereafter to move forwardly to operate upon the rear end thereof, a method which is found to give superior results in the finished upper.

The several features of the invention above mentioned and others including certain details of construction and combinations of parts will now be described with the aid of the accompanying drawings and the combinations for which protection is sought will then be pointed out in the claims.

Figure 1 is a. side elevation of the machine.

Fig. 2 is a plan view, showing that the machine is a duplex apparatus in one of the molding mechanisms of which work will stand under molding pressure while another upper is being arranged in the companion mechanism. The operating parts of the left hand mechanism are shown 1n thelr advanced, 'work treating positions While the devices of the right hand mechanism, with he parts above the wipers removed, are shown open. Fig. 3 is a front view, partly in vertical transverse section through one of the inside formers, and showing the work receiving relation of the grippers to that former. Fig. l is a vertical longitudinal section through the right hand mechanism of Fig. 2, showing the several parts in open, worlr receiving positions. Fig. 5 shows the same parts when the outside formers have been advanced and closed, the wipers being still retracted; Fig. 6 shows the wipers advanced and the work under pressure, as in the left hand mechanism of Fig. 2. Fig. 7 shows, in plan, the open position of the formers and wipers, as in Fig. 4:. Fig. 8 shows the closed positions of the same as in Fig. 6. Figs. 9 and 10 are two detail views of the gripper operating mechanism, Fig. 10 being a section on line 1010 of Fig. 9. Fig. 11 is a plan View showing the wipers open. Fig. 12 is a similar view showing the inside former thrust backwardly into the field of operation of the wipers and the wipers closed and advanced for laying the marginal portion of the upper materials over the heel seat face of the former. Fig. 13 is a side elevation of one of the side wipers shown in Figs. 11 and 12. Figs. 1% and 15 are respectively side and sectional views of the end wipers shown in Figs. 11 and 12.

Particular attentionhas been given to the arrangement and organization of the machine to provide for the operators convenience in presenting the work and watch.- ing the operation of the machine thereon as the work goes under pressure; and also to the construction of the machine for the pur pose of securing the requisite distribution of strength ofthe machine to resist rigidly the molding strains without rendering the ma chine unnecessarily heavy or massive. In these connections it may be pointed out, referring to Figs. 1, 2 and 3, that the working plane is arranged at a slight inclination to the horizontal and at an elevation allowing the operator tolook down into the work. The machine is open below the inside former. as best shown in Fig. 1, and also all around the former, see Fig. 2, to allow the work to be applied to the former from underneath andsupported while being put under compression. The support for resisting forward pressure against the inside former is a powerful yoke extended forwardly in the working plane of the machine and then upturned to a plane above the work engaged portions of the former as shown in Fig. 1. These characteristics contribute materially to the practical value of the machine.

Referring to Fig. 1, the column of the ma chine is bowed rearwardly and has bearings for a pulley shaft 2 that extends from rear to front of the machine and bears a clutch which is arranged to be closed by the elevation of treadle rod 4 through connections 5, 6, 7, 8 and 9, Fig. 1, with alost motion at 10 for a purpose which will later appear. The pulley shaft 2 has a worm by which, and a worm gear 12, it drives the cam shaft 15 extending at right angles to pulley shaft 2 and bearing cams from which the upper molding mechanisms are operated by power. The upper part of the machine frame is inclined forwardly and its top surface slopes downwardly toward the operator so that when he places an upper in the machine he can readily observe the location of the upstanding margin of the heel portion, thereby enabling him to locate the upper accurately with relation to the molding mechanisms. Mounted on the top of the frame are essee? e inner and outer heel molds, wipers for wiping inwardly the rear upstanding portion of the margin to form the inturned flange and to press the latter down upon the inner mold, and grippers to engage the shank portion of the margin to strain it forwardly against the rear end of the inner. mold and thus wardly relatively to the column in two lateral arms 19 as will be seen from Figs. 1 and 2, these forward extensions being provided between their outer ends with a crossbeam 20 having two guideways or seats on its under side, Figs. 1 and 3, for the reception of the inner molds 25. Each inner mold has, as best appears in Fig. 1, an upwardly and forwardly extended attaching portion which is shaped to fit its seat and has also a lip or shoulder-424 located to abut against the inner side of the crossbeam. A bolt 23 passes through the cr0ss-beam and is threaded into the inner mold. By these means the inner mold 25 is very rigidly supported against the stresses to which it is subjected, and yet is readily replaceable, while at the same time an unobstructed space for presentation, support and adjustment of the work is provided and maintained on all sides (Fig. 3) and in front (Fig. 1) of the inner mold. f

The outer mold is located directly behind the middle of the inner mold and comprises two formers 26, Figs. 2, 3 and 7, pivotally connected to a slide 28 upon which the forni-.

ers rest and by which they are upheld, F 4. The slide has a slotted connection with a supporting bolt 29, Fig. at, acted upon by a spring 30, thereby providing possibility for the formers 26 to yield downwardly to a slight extent under stress. Each of the two formers is also connected by a swivel joint to a link 32 having a similar connection with a pressure applying slider 35 that is actuated forwardly through two heavy helical springs 36, Fig. 2. The rear ends of these springs abut against a crosshead a0 which is connected to one end of the forward link 38 of a toggle, Fig. 1, the rear end of the other link 39 being pivoted to the frame of the machine. The junction of the two links of the toggle is connected to a depending yoke l2 actuated by a cam on the shaft 15.

The arrangement of the links 32, 32 and of their connections to the outside formers 26 is such that they exert an inward thrust at an inclination'to the direction of operative movement of the molds andthey also.

distribute theforming pressure evenly over the back part of the heel.

In order that the outside formers may be closed inbefore their back corners contact with theback of the upper, cam faces or inclines4c3 on the forward ends of these formers (Figs. 2 and 7 are provided which, durmg the forward movement of the formers, contact withrol ls 41 secured to the machine frame and push the formers together. This prevents the possibility of the back corners of the formers nipping the upper.

The wipers comprise twoside plates or wiper plate carriers 50 and a rear wiper 51,

Figs. 7 and 8, and 11 to 15, of which the two side wipers are pivotally supported near their rear ends at 52 upon a loose frame 54: that is located within the superstructure, Figs. 1, 5 and 6, which will be designated as the wiper carrying slide 55. I

The wipers50, like the outside formers 26,

normally stand wide apart and back away i from the insideformer as indicated in Figs. 7 and 11 to give ample room around the inside former 25 for the presentation and adjustment of the upper materials before the formers close. The wipers have cam or incline faces 56 that are held by a spring 57 against cam rolls 58 as shown in Fig. 7 and that close the wipers when the wipers first begin to advance before the rear wiper engages the work. idly attached to the frame or plate 5% which depresses the wipers for compressing the stock.

The advance movement of the wiper carrying slide 55, carrying with it the end wiper 51, is derived through connections with a bell crank 60, Fig. 1, which is fulcrumed to the frame and has its lower, backwardly bent arm connected with a rising and falling yoke actuated from a cam on the shaft 15. v The connection from the bell crank 60 to the slide 55 comprises a link 6% connectedcat its forward end to the depending arm 65 of a second bell crank Which has a rearwardly projecting arm 66 in Figs. 1, 2, 4t, 5, 6 carrying a roll 68overlying a cam track 70 on the frameavhich has a step at 72. The depending arm 65 is also connected by a link 74 to a. thrust bar 75 operating two wide toggles 76, 77, Figs. 4, 5 and 6, located between the wiper carrying slide and the loose frame or plate 54: to which the wipers 50 and 51 are connected, one toggle being arranged near each end of the loose frame. This; connection provides that the wiper carrying slideshall first be advanced with the wipers held, bythe action of cam 70 on arm 66, high enough above the heel seat face of inside former 25 to bend over and break down the upper materials upon the inside former and then, after the wipers .reach their fully closed position, roll 68 The rear wiper 51 1s r1g crank 65, 66 to turn about its pivotal connection to the wiper carrying slide and thereby to act through link 7 1 and thrust bar to straighten the toggles for depressing the wipers powerfully upon the heel seat after the completion of their forward movement. In the return movement step 72 raises the wipers at once to prevent outward drag on the work. This is done by rocking stiff springs the tension of which can be adjusted by screws 7 9. The toggles preferably comprise toothed engaging faces formed eccentrically to the pivots of the links and arranged for causing the toggles, as they are straightened, to press the wipers forcefully downward and lock them.

The grippers for engaging thework at opposite sides of the shoe and tensioning it forwardly about the inside former preparatory to the action of the formers are each operated by a sliding rod 80, Figs. 1, 2, 3, 9 and 10, each gripper and its operating means being substantially the same. The rod is arranged to extend horizontally from front to back of the machine in bearings attached to the frame and its rear end is toothed as shown in Fig. 1 and is connected by a pinion on the same shaft to the pinion 81, rack bar 82, bell crank 83, rod 8% and spring through to the lever 5 which is operated by the starting treadle. Upon the gripper rod 80 is a sleeve 86 confined between a rod bearing and a rearwardly acting spring 8'? Fig. 2, and having a cam slot 89 into which extends a cam roll carried by the rod 80. A radial arm 88 is adjustably mounted by clamp screw 89 upon the sleeve 86, the outer end of the arm being toothed to form one jaw of the gripper. Guideways are formed on the under side of this arm for a second arm which is arranged to slide in the guideways and carries on its outer end a second. jaw. A bell crank lever 90, Fig. 9, is pivoted to the radial arm 88 and its short arm engages the sliding jaw to move it for closing and opening the gripper. The other arm of lever 90 engages a stop face on rod 80, Fig. 9, so that when the rod is moved forwardly the gripper is closed. After the gripper has been closed further forward movement of the sliding rod 80 will carry it and the sleeve and the gripper against the action of spring 87, thus moving the upper toward the toe of the shoe and stretching it adequately about the heel end of the inner mold.

The described connection of gripper rod 80 with the starting treadle lever 5 provides that while the lost motion at 10 between lever 5 and the starting clutch is being used the rod 80 acts through hell crank 90 to close the jaws upon the work and then to advance the jaws to pull the upper forwardly. This is manually controlled movement and the work may be adjusted about the mold 25 or manipulated as it may require before the machine is started by the closing of theclutch. The pinion has a blank part which is brought opposite bar 82 to permit the necessary further depression of the treadle to start the machine. The gripper retains its hold until the outside formers move forwardly sufficiently far to press the materials upon the inner mold and then the forward movement of the wiper carrying slide carries the bell crank 88 with it, thus causing it to move the pinion reversely so that the sliding rod 80 is moved rearwardly to release the gripper. This is automatic in that it is obtained from the power mechanism. After the gripper has been released the rearward motion continues su'liiciently far to cause the cam groove in the sleeve 86 to rotate the sleeve and thus rock the gripper upwardly to remove it out of the way of the work. This rotational movement of the gripper is produced by movement of the cam roll in a spiral part of the cam groove. When the wiper carrying slide again retires at the conclusion of the machines cycle the gripper is returned to such a position level with the top of the inner mold that it is ready to grip a new upper when it is placed upon the mold. The inner mold is preferably heated by steam and is therefore provided with a steam chamber to and from which lead steam pipes 93 as in Fig. 3.

In the use of the machine the upper is ap plied upwardly to the inside former from underneath it, the clear space about the former, see Figs; 2, 3, 4: and 7 including the space directly in front of it, Fig. 1, for the reception of the forepart of the upper without distortion, making it possible to arrange the upper quickly and accurately and to watch from above the adjustment of the work. The upper and the ends of the heel stiffener at the shank are guided into the grippers which are then closed and advanced by the starting treadle. The operator may pause and relax the pull on the upper and rearrange it before starting the machine if itdoes not pull. satisfactorily about the inside former. Further depression of the treadle starts the power mechanism which closes the outside formers and then advances and finally depresses the wipers and comes 3 ion to rest with the work under compression to set, the inside former being preferably heated. As the wiper carrying slide advanced the grippers were released and were turned up as in Fig 3, left hand side. It will be understoodthat this is a duplex machine and that while the mechanism on one side of.

the machine has been Operated as described, that on the other, side has been restored to work receiving position, the outside formers being drawn back against springs 26 by the interlocking engagement of crosshea'd 40 with theslider 35, Fig. 7 and the grippers being turned down tothe position shown at the rightof Fig. 3. r
